Feelings of lack of energy after contrast may be relieved by rest, drinking plenty of fluids, elevation of the lower extremities, intravenous rehydration, oxygen by mask, and ineffective treatment with medications (epinephrine, atropine).
Acute or delayed adverse reactions may occur after contrast administration.
Acute adverse reactions include rash, pruritus, nausea and vomiting, chills and fever, simple hypotension, vagal reflexes, and in severe cases, severe vomiting, bronchospasm, shock, cardiac arrhythmias, and syncope may occur.
The occurrence of fatigue after contrast media is less frequently reported, and is considered to be caused by simple hypotension and vagal reflexes after the use of contrast media.
If the symptoms of fatigue are mild, you can just rest and drink plenty of water. Drinking water can promote the elimination of contrast medium and reduce the adverse effects.
If the weakness is severe and accompanied by simple hypotension (low blood pressure, fast heart rate, dizziness), it can be treated with elevation of the lower extremities, oxygen, intravenous rehydration, and, if all of the above are ineffective, epinephrine can be used.
Vagal reflex will appear low blood pressure with bradycardia, can be treated by elevating the lower limbs, oxygen, rapid rehydration, if necessary, can apply atropine.
Warm reminder: the emergence of adverse reactions need to promptly inform the medical care, timely treatment, so as not to delay the condition.
